Overview
SPEED provides various interfaces to the PS2, including Ethernet, where it functions as a MAC (using an external Ethernet transceiver/PHY), IDE/ATA and an UART (to which the modem connects in case of the north-american-only SCPH-10281 Network Adaptor and some north-american SCPH-700XX PS2 slim variants). It's connected to the PS2-side via SSBUS (PCMCIA in SCPH-1X000 consoles). For fat models, it comes inside the network adaptor. For slim models, it comes on the motherboard for SCPH-700XX consoles, with the IDE pins still exposed on the PCB, making it possible to connect a hard drive (which is, however, not practical in most cases, as it requires a lot of wires and soldering). Starting with SCPH-750XX consoles, SPEED was not used anymore, as its functions of an network controller were integrated into the newly developed PPC405-based IOP/Deckard, with the IDE interface being removed entirely.
PSX has two SPEED-ICs, with one of them being a CXD9731GP (see list below) and the other one being a (physically larger) CXD9764GP.
Additionaly, it is connected to an external 1k Bit / 128 Bytes EEPROM in both, the Network Adaptor and in SCPH-700XX consoles. In the PSX, the EEPROM is connected to the larger CXD9764GP.
The die of SPEED has some IBM-markings, which suggest it's been manufactured and potentially developed by IBM.
It is packaged in a 196 (14x14) pin BGA case.
